W1700k Openwrt Hot Guide

However, "W1700K" is not a standard OpenWrt target in the official table of hardware. It might be:

• A typo or model number from a custom firmware build (e.g., from Chinese manufacturers like ZTE, Xiaomi, or MediaTek reference boards).
• A USB WiFi adapter chipset (rare).
• A misspelling of MT7621 or similar SoC device.

Given the context, I’ll provide a generic OpenWrt overheating troubleshooting and cooling guide that applies to most routers, including unknown models like "W1700K". You can adapt it once you confirm the exact hardware.

Step 2: Connect to Your Router via SSH

1. Connect your computer to your W1700K via Ethernet cable.
2. Open PuTTY (or similar software) and create a new connection:
   • Host: 192.168.0.1 (or the IP address of your router)
   • Port: 22
   • Connection Type: SSH
3. Click "Open" to connect to your router.

5. Monitor temperature (if sensor exists)

# Common paths
cat /sys/class/thermal/thermal_zone0/temp
cat /sys/class/hwmon/hwmon0/temp1_input

Divide by 1000 for Celsius.

Install lm-sensors:

opkg install lm-sensors
sensors

4. Summer Ambient Temperatures

Many users search for "hot" in July and August. The W1700K relies on passive convection. If your ambient room temperature is 30°C (86°F), the internal temperature will easily hit 80°C–85°C.

6. Disable Unused Services

OpenWrt turns on many services by default. Disable:

• Bandwidth monitoring (if not needed)
• Full-cone NAT (unless gaming)
• Debug logs (dmesg spam creates heat)

Go to System > Startup and stop odhcpd if using static IPs. w1700k openwrt hot

Why is it "Hot" Right Now?

The surge in popularity isn't just about the specs; it’s about the price-to-performance ratio.

1. The "Flash" Factor The W1700K has become a darling of the "salt fish" (second-hand market) community. These units are often available for incredibly low prices (often under $20-$30 USD equivalent). For hobbyists looking to build a mesh network or set up a dedicated VPN gateway, the cost of entry is negligible.

2. OpenWrt Compatibility The router has received robust support from the open-source community. Unlike some Broadcom-based routers which have poor wireless driver support in Linux, the W1700K generally utilizes chipsets that play nicely with the Linux kernel. This means users don’t have to sacrifice Wi-Fi speeds to enjoy the stability of OpenWrt. However, "W1700K" is not a standard OpenWrt target

3. Stability Many users are migrating to the W1700K to replace routers that crash under heavy P2P loads (like BitTorrent). The combination of a solid CPU and generous RAM allows the router to handle thousands of concurrent connections without the memory leaks that plague stock ISP firmware.

3. Wi-Fi Driver Aggressiveness

The stock firmware uses proprietary drivers that sleep between beacon intervals. OpenWrt’s open-source drivers (like mt76) keep radios active for better roaming and fast handoffs. The W1700K’s 4x4 MIMO radios generate significant heat—often hotter than the CPU itself.
